RAILWAY-SWITCH.

I To all whom it may concern.

'of Vigo and State of Indiana, have 'invented. certain new and useful Improve ments in Railway-Switches; and we do departs to be hereinafter fully described and claimed, the descrlptlve matter being sup- 'clare the following to bea full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates broadly to improvements in railway switches, and more particularly to the connection of the bridlebars thereof with the operating bars which are actuated by suitable mechanism disposed to one side of the track.

' The object of the invention is to improve upon the construction of connections of the class described to such an extent as to allow the bridle bar to shift independently of the operating bar under certain conditions to be set forth.

With this general object in View, the invention resides in certainnovel features of construction and in unique combinations of plemented by the accompanying drawings wherein: v a

Figure 1 is atop planview of a railway switch constructed in accordance with the invention Fig. 2 is-a vertical transverse section viewed on the plane of the line 22 of Fig. 1; Fig. 3 is a similar view showing a different position of parts; Fig. 4 is a detail vertical section taken .on the plane in dicated by the line 4 1 of Fig. 3; 5 is a perspective detail showing more particularly the construction of the bridle bar; Fig. 6 is a perspective view of the operat ng bar, and Fig. 7 is a similar view of the spring connection between the two bars. a

1n thesedrawings. which constitute apart ofthe application, and in which like reference characters designate corresponding parts throughout the several views, 1ndicates broadly the main line of a railway track, S representsa-siding, and T designates the usual switch tongues which control the passage of rolling stock onto the siding or the main track according to requirements.

Pivoted at its opposite ends by any preferred means to the switch tongues T, is a horizontal bridle bar 1 whose intermediate Specification of Letters Yatent.

portion is offset laterally as disclosed at 2 to provide a gap between the endsof the bar, the portion 2 being preferably though not necessarily ofiset upwardly as shown in Figs. 2 and 3.

Formed integrally with one end portion of the bar 1, and projecting into one end of the gap in substantial alinement with both ends of the bar in question, is a horizontal stop lug 3 upon which one end of afiat horizontal spring-4 bears, the other end of said spring being bent upwardly and laterally as disclosed at 5 and being riveted or otherwise secured to the ofiset central portion 2 of, the bar 1.

v Slidalole longitudinally in respect to the shoulders formed on the spring 4 by bowing.

spaced portions of said spring upwardly as disclosed at 11 in Figs. 2, 3 and 7.

For shiftingthe operating bar 6 longitudinally to control the positions of the switch tongues T. practically any preferred means may be provided, but a link 12 preferably connects oneend of said bar with an upright lever 13 fulcrumed between its ends to. an upright standard 14 rising from a bed plate 15 which is spiked or otherwise se- The upper end of the lever 13 is provided with a slot 16 receiving therein a stud 17-onthe shorter arm of a vertically swinging bell crank lever 18, the latter being pivoted at its angle to the upper end of the standard 1 1 and having its longer arm weighted and formed with an opening 19 to receive therein the perforated bar 20 which projects laterally from the standard 14:. By this arrangement ofparts, a lock 21 (see Figs. 2 and 3) may be applied to lock the lever 18 lowered to retain the switch in closed position, but when said lever is raised to open the switch as shown in Figs. 1 and 2, the lock may be used to hold it in raised position.

semaphore blade 22 carried the upper end of a shaft 23 which rises from and isrota-r tably supported by the bed plate 15, the

lower end of said shaft being equipped with a crank arm connected by a link with the link 12. -This construction will operate the ;v

semaphore blade '12 simultaneously with opening and closing of theswitc'h' to display the condition of the latter. V

'The device above described is designed primarily for use upon single track railways on'which trains traveling in one direction must run upon a blind siding to await the passage of another train in the opposite direction. When so applied to use, the switch tongues may be positioned as shown in full lines in Fig. 1 whereupon the train I moving in the direction of the arrow A. may

travel upon the siding S, the connection between the bridle bar 1 and theoperating bar 6 now assuming the position shown in- Fig. 2. The tongues T may now remain in the position at which they have'been previously set, since the second train traveling in the directionof the arrow B will, by the contact of its wheel flanges with the tongues T, throw themto the dotted line position shown in Fig. 1, this being allowed by the spring 4: which yields upwardly when the tongues T and the bridle bar 1 are shiftedfr-om one position to the other. The train upon the siding may now travel in the di rection of the arrow C onto the main track,

ber of advantageous characteristics.

In the drawings, certain specific details of construction have been shown for accom;v

plishing probably the best results, and in the preceding such details have been described, but obviously; we need not be restricted thereto otherwise than to the extent to which the appended claims limit us.

We claim y I 1.j'In a switch, a pair of horizontal bars disposed side by side and slidable in respect to each other, a horizontal spring secured to one bar, and coacting stop shoulders on the spring and on the other bar; in combination with a. pair of switch Copies of this patent may be obtained for 2.
